3. © 2003 IBM Corporation 1.J2EE Overview  The Java 2 Platform, Enterprise Edition (J2EE) defines the standard for developing multitier enterprise applications.  Portable and scalable standards

4. © 2003 IBM Corporation J2EE application model :

5. © 2003 IBM Corporation 2. Enterprise System Requirement :  High Availability  Load Balancing  Failover  Scalability  Security  maintainability

6. © 2003 IBM Corporation 3. J2EE Components :  Enterprise Java Bean (EJB)  JavaServer Page (JSP)  Java Naming and Directory Interface (JNDI)  Java Messaging Service (JMS)  Java Database Connectivity (JDBC)  Java Transaction API (JTA)  Remote Method Invocation/Internet Inter-ORB Protocol (RMI-IIOP)  J2EE Connector Architecture  Java Authentication and Authorization Service

7. © 2003 IBM Corporation JNDI ( Java Naming and Directory Interface ) : Naming and directory Services are used to form a structured hierarchy of items that must be made available to distributed program. JMS : Java messaging Service -Is a Java API for accessing message-oriented middleware

8. © 2003 IBM Corporation JDBC : Java Database Connectivity - A standard Java Interface for accessing heterogeneous database - A specification that defines four drivers type for connecting to database JTA : Java transaction API - A Java Transaction API is a standard java API for demarcating transactions within a program - WebLogic Server Supports local and distributed transactions

10. © 2003 IBM Corporation Web Client Web Server Application Server Proxy Server Firewall Server ….explained Machine ….explained Cluster ….explained Domain ….explained Administration Server ….explained Managed Server ….explained

11. © 2003 IBM Corporation Server : -A Server is an instance of weblogic.Server executing in JVM -Runs on designated WLS machine -Has a dedicated amount of RAM -Is multithreaded Domain - A Cluster -- Machine 1 ---- Machine 2 -- Server A Server D Server C Server B Server E

12. © 2003 IBM Corporation Domain - A Cluster -- Machine 1 ---- Machine 2 -- Server A Server D Server C Server B Server E Machine : -A Machine is a physical computer that hosts Weblogic Server. -Can host multiple WebLogic Server

13. © 2003 IBM Corporation Domain - A Cluster -- Machine 1 ---- Machine 2 -- Server A Server D Server C Server B Server E Cluster : -A Cluster is a logical group of WLS server -Provides automatic Fault Tolerance, High Availability, Load balancing -Transparent to client

14. © 2003 IBM Corporation Domain - A Cluster -- Machine 1 ---- Machine 2 -- Server A Server D Server C Server B Server E Domain : -Provides ONE point of Administration Server -A domain is a logically related group of WebLogic Server resources that you manage as a unit

15. © 2003 IBM Corporation Administration Server : -An administration Server is the central point of control for domain -Stores the configuration information and logs for a domain -Runs Weblogic administration console Managed Server : -Any server in the domain that is not the Admin Server -Contacts Admin server for configuration information

38. © 2003 IBM Corporation 1.JVM -Xms The minimum size of the dynamic heap -Xms The maximum size of the dynamic heap

39. © 2003 IBM Corporation 2. CLASSPATH To run WLS, you must configure : -Path to include all executable programs (including JAVA interpreter) -CLASSPATH to include dependencies
